Try something like this: mydict <- lapply(mylist, valfun) names(mydict) <- sapply(mylist, keyfun) or mydict <- structure(lapply(mylist, valfun), names=sapply(mylist, keyfun)) Cheers Olaf ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
